DRAM Dips Premarket: Samsung, SK Hynix Announce $590B Expansion Push As South Korea Plans To Double DRAM Capacity - Stocktwits

The recent dip in DRAM market opening contrasts sharply with major announcements from Samsung and SK Hynix regarding a $590 billion expansion plan, while South Korea plans to double its DRAM capacity.... Read original →

South Korea’s $590B DRAM expansion with Samsung and SK Hynix isn’t just capacity scaling—it’s a strategic bet on AI-driven memory architecture shifts. Technically, this accelerates the displacement of commodity DRAM by HBM and GDDR7, forcing TSMC, Micron, and firms in Taiwan, China to fast-track CoWoS and 3D stacking. U.S. export controls on advanced tools could raise Korean fab costs by 15–20%, though domestic subsidies mitigate some exposure. Competitively, Micron may delay its Hiroshima Phase II and deepen CXL-based memory pooling collaboration with Intel, while China’s CXMT targets niche commodity segments. Over the next 18 months, the market faces 'phantom oversupply': headline capacity surges, yet high-end supply remains tight, amplifying price volatility and squeezing smaller module makers.
